Description of the invention (1) The present invention relates to a bicycle brake assembly. More specifically, the present invention relates to a brake fixing mechanism for connecting a bicycle brake device to a front fork or a rear fork of a bicycle, so that the brake block of the brake device is pressed against the corresponding wheel when the brake operating device is actuated. On the rims. Cycling is gradually becoming one of the most popular forms of entertainment and a means of transportation. Moreover, cycling is becoming a very popular competitive sport for amateur and professional athletes. Whether the bicycle is used for recreation 'transportation or competition, the bicycle industry has been improving various components of the bicycle. A special component of bicycles that have been extensively redesigned in the past few years is the bicycle brake. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) There are several types of bicycle brake devices currently available in the market. Examples of several types of ordinary bicycle brake devices include rim brakes and caliper brakes. Regarding the caliper brake, there are mainly three types of caliper brakes: side pull type, center pull type and cantilever type. In the side pull type caliper brake, a pair of brake arms are pivotally connected around a center mounting bolt 'which is attached to a bicycle frame. The brake arms each have a lever portion that is connected to the brake lever so that when a rider manipulates the brake lever of the brake operating device, the lever portions of the brake arm are pulled together, which in turn drives the The brake pads on the other end are pressed against the rim of the bicycle wheel together. When the rider releases the brake lever, a return spring is provided to bias the brake arm away from the bicycle wheel rim. The operation of the center pull type caliper brake is similar to that of the side pull type, except that the brake arm is attached to a brake arm jumper so that each brake arm is pivotally connected to an independent one on the brake arm jumper. On the pivot point. This paper size applies to Chinese National Standard (CNS) A4 (210X297 mm) -4-Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 ___B7 V. Description of the invention (2) The brake arm jumper is directly attached to the bicycle On the frame. A fork cable connects the two lever sections of the brake arm to each other so that the main brake cable is connected to the fork cable to pull the lever portion of the brake arm together. Cantilever brakes are generally mounted on bicycles designed for off-road use like mountain bikes (MTB) and all sports cars (A T B). In particular, the cantilever brake device is designed to provide strong braking force. The cantilever brake device is equipped with a pair of brake arms that are rotatably supported on the front or rear fork of the bicycle frame in a cantilever manner, and the brake pads are attached to the middle or upper portion of the brake arm. " In general, the lower end of the brake arm is rotatably supported on the frame, while the upper end is connected to the brake cable or wire. The brake pads are placed opposite each other on either side of the rim of the bicycle wheel between the brake arms. For this type of cantilever brake device, the bicycle arm turns in the direction of approaching each other when the brake cable is pulled by the brake lever. This will cause the brake pads to press against the rim in order to apply a braking force. For this cantilevered brake device, it is not necessary to change the shape of the bicycle according to the size of the bicycle as is possible with a side-pull caliper brake. Moreover, the cantilever brake device applies a more uniform braking force than the side pull type caliper brake. However, one disadvantage of conventional cantilever brakes is that the positioning portion of the brake arm is fixed to a pivot point welded to the frame. So the size of the 'pivot point' can vary depending on the design of the frame. And the welding accuracy of the 'pivot point' to the bicycle frame often changes with the quality of the bicycle frame. This will affect the performance of the brake device. According to the above, such a braking device is needed. The braking device is based on (read the precautions on the back before writing this page)%,
